Title: Children's air cushion travel bed
Inventor: KITTLER ELKE
IPC: A47D7/00
Filed: 1984-10-06
Abstract: The invention solves space, weight and construction problems of conventional travel beds due to the inflatability of the air cushion travel bed by means of a bellows. It consists of an inflatable lying surface and inflatable peripheral side walls in a multi-chamber system. The material is coated fabric.

Title: Telecommunications system having a plurality of subscriber stations which access a transmission medium with a ring structure
Inventor: STRATEN GERNOT VON DER
IPC: H04L12/433
Filed: 1985-03-04
Abstract: In a local area network having a plurality of stations which access a unidirectional ring in which each station which wishes to transmit initially listens in to the ring line to determine whether a transmission process is already taking place there and, if the ring line is busy, waits for access until, by means of a token, it receives access authorization while, if the ring line is free, it accesses the ring line, in competition with other stations, with the risk of collision, if it does not already have an information packet in the ring which has been transmitted earlier and has been terminated by a token, if a collision is detected, the transmission of the information packet is interrupted and a collision packet is transmitted; on reception of such a collision packet, the ring is closed again and the station which wishes to transmit does not start to listen in to the ring line again until a randomly determined waiting-time interval has elapsed, unless it has already recognised a token and gained access.

Patent DE-3600531-A1 (DE)
Title: Device for producing single-crystal semiconductor material
Inventor: KELLER WOLFGANG DR RER NAT
IPC: C30B13/20
Filed: 1986-01-10
Abstract: During production of single-crystal semiconductor rods from multi-crystal semiconductor rods, the semiconductor rod is inductively heated by means of a HF heating coil (2), so that a melting zone (7) is formed in the semiconductor rod. A constant magnetic field is set up in addition at the electrically conductive melting zone (7) and forms the pole shoes (4) of a constant field magnet (3) which is made of ferromagnetic material. To ensure that the high frequency alternating field which is generated in the pole shoes (4) by the HF heating coil (2) is unable to cause a high degree of eddy current loss, the said pole shoes (4) are coated with a layer (5) of a highly electrically conductive material. <IMAGE>
Patent DE-3600818-A1 (DE)
Title: Skin-holding device
Inventor: SCHNELL KARL
IPC: A22C11/02
Filed: 1986-01-14
Abstract: The skin-holding device has at least two filling tubes (18, 19), which are arranged at an angle (17) and one of which is situated in the operating position in each case. They are held on a rotary valve (16) which in each case hydraulically connects the filling pipe, which is situated in the operating position, to an outlet channel (2) of a filling machine (1). The braking device (24), which is assigned to the end (30) of the filling pipe, for the gathered sausage skin (20) can be pulled off and/or pushed on, especially in a pneumatic manner. While the gathered sausage skin is being pulled off one filling pipe (18) and filled by the sausage meat, another gathered sausage skin (20) can be pushed onto the other filling pipe which is in the waiting position. This means that the transition from one gathered sausage skin to another can be carried out rapidly and, in particular, automatically stopped. In order to prevent the outside emergence of the filling material from the filling pipe which is in the operating position, the presence of the gathered sausage skin is continuously detected by means of a monitoring device (65). As soon as the rear end, in the flow direction, of the gathered sausage skin has passed this monitoring device (65), the filling pump of the filling machine (1) is switched off, after a delay (69) if necessary. The adjustability of at least the receiver (67) of the opto-electrical monitoring device (65) makes it possible for the monitoring device (65) to adapt to different diameters of the gathered sausage skin (20). <IMAGE>

Title: Vapour protection device for kitchen cupboards and worktops of a unit kitchen or the like
Inventor: ROHDE REINHARD
IPC: A47L15/42
Filed: 1986-01-14
Abstract: In the case of a vapour protection device for kitchen cupboards and worktops of a unit kitchen or the like, which delimit a niche space for a dishwasher for example, the underside of the worktop and its front face are at least partly covered by a vapour protection plate. In addition to the vapour protection plate connected to the worktop, the cupboard sides of the kitchen cupboards laterally delimiting the niche space are each provided with a protective cover extending as far as the vapour protection plate. As a result of this measure, an effective vapour protection is also provided for the furniture surfaces laterally delimiting the niche space for the built-in appliance, so that an effective screening of the endangered cupboard and worktop regions from steam and moisture is produced. At the same time, the vapour protection plates form smooth surfaces which are easy to clean.
Patent DE-3613868-A1 (DE)
Title: Gear for transmitting torques
Inventor: JOHNSON LARS
IPC: F16H1/16
Filed: 1986-04-24
Abstract: In a worm gear with a worm screw (1) and a worm wheel (2), the self-locking is achieved by the worm screw (1) being axially displaceable on a shaft (4). A driver (11) on the shaft (4) is arranged in a rhomboidal recess in a sleeve (5), on which the worm screw (1) is fastened. During driving of the shaft (4), the driver (11) is displaced into a corner of the recess, the sleeve (5) and the worm screw (1) being displaced axially into a central position so that the friction surfaces (6, 8 and 7, 9) run freely thereon and on a fixed machine part (10). When the shaft (4) is not driven, a reaction moment which acts on the worm screw (1) and is caused by a torque of the worm wheel (2) has the effect that a pair of the friction surfaces (6, 8) or (7, 9) comes into contact and brakes the worm screw (1), as a result of which self-locking is achieved. <IMAGE>
